Fly Ash Bricks

Fly Ash Bricks are manufactured using Fly Ash (a waste material from thermal power plant), Stone Dust, and Cement (OPC Grade). Their manufacturing eliminates fly ash from the environment as a pollutant and at the same time provides a green building material to the construction industry. There is a big market for Fly Ash bricks; the only thing required is awareness about its benefits. Even, the government is supporting its production and use in building construction, construction of pavements, dams, tanks, under waterworks, canal lining, irrigation work, etc.

Advantages of Fly Ash Bricks

High Compressive Strength:

NexGen Bricks have dense composition and high compressive strength which gives them higher load bearing capacity as compared to clay bricks. Also, they have almost nil wastage during transportation.

Light Weight:

NexGen Bricks are 12% lighter as compared to clay bricks. Therefore, it is suitable for multi-storey building; lesser weight means reduction in building's dead load, and thus less stress on building, safety assured.

Uniform Size & Shape:

NexGen Bricks are uniform in shape and size (9 x 4.25 x 3 inches) and have a far better finish as compared to clay bricks whose shape and size varies as they are handmade.

Automated Manufacturing:

NexGen Bricks are manufactured through an automated process which control the raw material ratios, uniform mixing, uniform and specified pressing loads which assures consistency in brick quality.

Thermal Insulation:

NexGen Bricks have better thermal insulation than clay bricks. They don't absorb heat; rather, they reflect heat. Therefore, they keep the interiors of buildings/houses cooler even in summer; hence they are more suitable for local conditions and can help to save on electricity bill.

Optimum Water Absorption:

They are less porous, absorbs less water, whereas burnt clay bricks absorbs more water during construction. Therefore, they help in water saving during construction and reduce chances of dampness on walls during rainy season. NexGen Bricks have optimum water absorption of about 12-13% required for plastering unlike cement bricks that have water absorption of about 5-6%, thus making them difficult for plastering.

Ease of Working:

Owing to its optimum strength, NexGen Bricks can be drilled, sawed, nailed and chiseled very conveniently with both manual and power driven tools without chipping or cracking, unlike cement bricks which cannot be drilled or chiselled using manual tools and gets cracked because of its unusually high compressive strength.

Noise Insulation:

NexGen Bricks are twice better in noise insulation than clay bricks.

Energy Efficient:

NexGen bricks are environment friendly as it is a 100% green building product. Their process of manufacturing is less energy intensive as compared to clay bricks. They help in keeping environment clean as they use Fly Ash (more than 50% of its weight), thus provides the most constructive solution to nation's fly ash utilization problem.

Pest Resistant:

With solid wall construction and finishes, there are fewer, if any, cavities for insects and rodents to dwell in. Being made of inorganic materials, NexGen bricks do not promote growth of molds & pests.

Cost Saving:

Cost Impact Analysis Compared to Bricks
Cost Component	Saving in Component	Estimated Impact on Project Cost	Explanation
Mortal Material	40%	2%	NexGen Bricks has a width of 4.25 inches, thus in external walls of 9 inches only 0.5 inch of mortar is required between two bricks compared to 1 inch mortar which is required in case of clay bricks.
Plastering Material	45%	3%	Exceptional dimensional accuracy & uniform shape, eliminates need of three-coat plaster walls and allows for a final 6 mm skin coat (putty/gypsum plaster)
Wastage	12%	0.5%	Breakage in bricks might be as high as 15% which in case of NexGen Bricks is less than 3%
Labour	20%	3%	Due to its dimensional accuracy and lower plaster requirement it provides 20% faster construction
Total Impact on Project Cost		8.5%

Quick Facts about Fly Ash Bricks

• Continuing use of clay bricks in construction industry will lead to extensive loss of fertile top soil. This could have a devastating environmental hazard.
• High demand for clay bricks would result in their price rise. To keep the cost of building materials in reasonable range, we should opt in for alternative building materials like Fly Ash bricks.
• Making use of Fly Ash bricks or other alternative building materials could slow down the rate of deforestation. Every year, a vast area of forest is destroyed in search of soil for brick manufacturing.
• Burnt clay bricks are manufactured using old outdated technology and no quality testing facilities are available at manufacturing site. Most bricks which are manufactured using outdated technology are inferior in quality with low compressive strength. They are not suitable for multi-storey buildings.
• Modern Fly ash bricks are manufactured using high end pre-programmed hydraulic machines. Bricks from these machines are tested for its quality and durability.

The current Fly Ash industry in India is about 163 million tones. This comprises the 12,000 existing units that are catering to the demand. Since the growth of the industry has been exponential till now, it can lead to a phenomenal growth of 50,000 units in the next ten years. Looking at the current growth, the market is expected to grow five times in the next decade. DNA Newspaper
